Description

Technical Field

[0001] The invention relates to the technical field of sludge dewatering treatment, and in particular to a sludge dewatering device for water conservancy river ecological treatment. Background Art

[0002] Underwater sludge usually refers to a mixture of clay, sediment, organic matter and various minerals, which is formed by the deposition of the bottom of the water after a long period of physical, chemical and biological effects. Underwater sludge can reflect the historical process of water evolution and is an important part of the natural water ecosystem such as rivers, lakes and river estuaries. Underwater sludge pollution can be divided into organic pollution and inorganic pollution. Inorganic pollution can be divided into eutrophication pollution such as nitrogen and phosphorus and heavy metal pollution. They are characterized by long-term, cumulative, latent and irreversible, and can be enriched thousands of times through the food chain, ultimately endangering human health.

[0057] The implementation principle of a sludge dewatering device for ecological management of water conservancy rivers in the embodiment of the present application is as follows: first, the external sludge pipe is placed into the dewatering cylinder 3 through the opening 50, and the sludge is transported to the dewatering cylinder 3, and then the servo motor 4 is started by the controller 49, and the output shaft of the servo motor 4 drives the driving rod 25 to rotate. Due to the meshing between the driving gear 26 and the gear ring 27, the driving rod 25 drives the gear ring 27 to rotate through the driving gear 26, and the gear ring 27 drives the fixedly connected dewatering cylinder 3 to rotate, and the centrifugal force is used to make the sewage in the sludge separate from the dewatering cylinder 3 and slide into the mixing box 10 along the two liquid guide plates 36. At the same time, the driving rod 25 drives the cam 37 to rotate, and reciprocates to squeeze the L-shaped plate 38 to move, and the L-shaped plate 38 moves to drive the mixing box 10 moves, so that the left support block 11 fixedly connected to the mixing box 10 slides in the reset groove 40 and compresses the reset spring 41. When the reset spring 41 releases its elastic force, it can drive the left support block 11 to reset, thereby achieving the effect of shaking the mixing box 10, so that the sewage and the purifier in the mixing box 10 are mixed. At the same time, when the mixing box 10 reciprocates, the moving gear 45 can be meshed with the fixed rack 42, and the moving gear 45 rotates and drives the stirring blade 44 to rotate, thereby achieving the effect of fully stirring the sewage, and then the sewage can be effectively treated. The cylinder 21 is started by the controller 49, and the cylinder 21 drives the forming circular plate 22 to move downward, enter the dehydration cylinder 3, and squeeze the sludge in the dehydration cylinder 3, thereby achieving the secondary dehydration effect. When the sludge is compressed and formed, the controller 49 starts the push rod motor 6, so that the output shaft of the push rod motor 6 drives the discharge plate 7 to move. Since the discharge plate 7 is provided with a groove, and the groove is adapted to the bottom of the dewatering cylinder 3, when the discharge plate 7 moves, the sludge block formed in the groove is moved out of the dewatering box 1 through the discharge port 8, so that the staff can handle the formed sludge block. After dehydration, the controller 49 is used to start the water pump 15, so that the water pump 15 draws out the water in the water storage cylinder 13 through the water pipe 14, and transports it to the water spray plate 18 through the water pipe 20, and then sprays it to the dewatering cylinder 3 through multiple nozzles 19, so as to achieve the effect of flushing the dewatering cylinder 3. The flushing water can flow into the mixing box 10 through the two liquid guide plates 36 to beat. The lid 56 is opened, and the water after cleaning can be discharged through the drain pipe 55. At the same time, the driving rod 25 drives the fixedly connected No. 1 bevel gear 28 to rotate. Due to the meshing between the No. 1 bevel gear 28 and the No. 2 bevel gear 31, the driving rod 25 drives the No. 2 bevel gear 31 to rotate through the No. 1 bevel gear 28, and the No. 2 bevel gear 31 drives the fixedly connected rotating rod 30 to rotate. The rotating rod 30 drives the fixedly connected fan blade cover 32 to rotate, and the exhaust fan blades 33 fixedly connected to the fan blade cover 32 rotate to draw the outside air into the air inlet box 12. After being filtered by the filter plate 35, the air enters the blowing cover 34 through the air inlet box 12 and is blown to the air guide plate 16. Since the air guide plate 16 is inclined, the air flow is reflected and dispersed in the air inlet box 12.This ensures air circulation in the dehydration box 1, avoids moisture regeneration, and reduces its service life.
